Sitting in front of the alchemy table, Bernard seriously pondered a crystal lens, like an eyeglass craftsman in the last century, carefully adjusting the angle and slowly polishing the lens in his hand.

Dawn Crystal is a very peculiar magical material, and it is also one of the few materials in the wizarding world that is difficult to reconcile and shape with magic, so Bernard has to grind the lenses here so hard for his glasses.

"It's finally good!" Bernard, who was infinitely resentful, let out a pleasant howl in his heart.

Looking at the two lenses placed in front of him, Bernard had a feeling that he was about to be moved by his own tears, wiped away the tears that did not exist, and regained his serious faceBernard, gently picked up the two lenses and walked to a pool on the other side.

When I put the lens in my hand sideways into the pool, I saw the round lens swaying from side to side in the water, and then gradually fell to the bottom of the water.

After putting away the lenses, Bernard picked up the two test tubes next to the pool, gritted his teeth, poured the strange liquid in the test tubes into the pool, and watched the liquid slowly blur in the pool, blend, and then disappear into the water.

One second, two seconds...... Five seconds passed, and there was still no reaction in the pool, and Bernard, who had been nervous since the beginning of pouring the potion, finally had to accept that he seemed to have failed. A disappointed Bernard waved his wand, and the polluted water in the pool disappeared completely.

Ignoring the lenses lying quietly at the bottom of the pool, Bernard tapped his wand, and the hose above the pool began to slowly fill the pool. Bernard, on the other hand, came to a small cauldron, lit a strange blue fire, and began to slowly add some strange things to the pot.

The dry stool of the fox, the wings of the fairy, the juice of the orchid...... As Bernard added the potion ingredients to the cauldron and stirred them clockwise as recorded in the book, once or twice, Bernard began to wonder about the correctness of the recipe in the process of this simple repetition.

It has been said before that Potions was once part of the discipline of alchemy in ancient times, when it was called plant alchemy, and now, this recipe of Bernard is a relic of that era.

In the world of Harry Potter, as long as there is any evil and powerful magic, it will definitely be able to talk about ancient times, which makes the wizarding world seem to have only two eras: modern and ancient, and in this regard, Bernard can only say, sorry, it's really like this.

Of course, the history of the wizarding world will never be so simple, but this simple division of the era is indeed an intentional practice of the upper echelons of the entire wizarding world. Behind this, it is natural to dilute some truths that the public does not want to know, so the information barrier exists, whether in the Muggle world or in the wizarding world.

The modern era of the wizarding world has always been clear, from the founding of Hogwarts to the present day. The reason why this is calculated is because the establishment of Hogwarts represents the official breaking of the family-based way of learning magic in Europe, and the monopoly of pure-bloods has slowly gone to a low point from that day.

For this reason, this day is unanimously recognized by scholars of the history of magic in Europe as the beginning of the modern era of European magic history.

So, the modern era of the European magical world is only more than 1,000 years, and before this day, I'm sorry it was called ancient, why is this so? First of all, in modern times, several great wars are clearly on the books, the rebellion of the elves, the witch hunts of the Muggles, and the great wars between wizards...... These wars have destroyed many precious manuscripts.

Some of the materials have since been lost, which is a natural pity for the European wizarding community. But that's not a problem, the history of magic in our European wizarding world is broken, isn't there the Americas, Asia, and Africa! At a time when these scholars of the history of magic were enthusiastically engaged in the study of these histories.

It was only then to the horror of everyone that the materials kept in the Americas and Africa, as well as India, Japan, and other countries in addition to the unverifiable Europe, were all faulty at the same time, as if a powerful force had erased all records of the world at the same time.

When this problem was first discovered, it caused a great panic, and it was not a frightening thing that the entire world, except for the United Kingdom, which has been dissipated, and China, which is undetectable, have all had a fault line in their history at the same time.

In order to deal with this matter, the International Federation of Wizards also specially appointed a wizard representative at that time, and visited the ancestral land of the elves, Avalon, as the most powerful magical group in the wizarding world in addition to wizards, the elves' long lifespan left them a detailed history, and it is said that the elves also have their own set of written records to prevent the fault of civilization.

But when Dumbledore returned to the International Confederation of Wizards, a strange mood spread among the upper echelons of the wizarding world, and since then, the history of magic textbooks in the wizarding world have all started in modern times, and they have all become tedious and boring, which can be very fatal to young wizards.

Not everyone is like Hermione, willing to take every discipline seriously, for most young wizards, Quidditch, chess, and romance are much more interesting than the boring history of magic, so under the cold treatment, the truth is slowly covered up.

If it weren't for the fact that his mentor had mentioned it when talking about the development of alchemy, with Bernard's qualifications, it would have been impossible to know this kind of secret, and similarly, Bernard also knew another thing, that is, although magic has been declining in modern times, alchemy has been flourishing.

Whether it is pioneering and enterprising, or inheriting and innovating, alchemists have done a good job, and the representative of them is the separation of plant alchemy and the emergence of harmonizing alchemy, which are the biggest advances in modern alchemy.

Among them, the Potions family has the most contribution from the Prince family and the Granger family, and in the field of harmonic alchemy, it has reached its peak with his mentor Nick Lemay refining the Philosopher's Stone, of course, according to the mentor, the blended alchemy is likely to be developing in the alchemy before the fault, which Bernard does not comment.

Retracting his thoughts, looking at the milky white liquid boiled into a milky white liquid, Bernard nodded with satisfaction, and then added a small spoonful of dissociation stone powder to it, as if it was a differentiator, as soon as the light blue dissociation stone powder entered the crucible, the milky white juice began to slowly settle and separate.

The top one turned into a clear liquid, and the bottom one turned into a white catkins-like thing, and after careful comparison, I found that it was no different from before, and Bernard, who was "groaning" in his heart, continued to wave his wand calmly and divided the liquid medicine into two test tubes.

Picked up the test tube, strode to the pool, looked at the pool filled with clean water, "boom", the liquid in the test tube was poured into it by Bernard at once, unlike last time, the liquid medicine had just entered the water, and the whole pool water seemed to be boiling, and began to bubble out wildly.

It was at this time that Bernard's eyes flashed, and he pointed to the two lenses in the pool and began to cast spells, "all protection", "deaf and clear", and "magic manifested"...... These spells act as catalysts, and as soon as the unique magic fluctuations come into contact with the pool, they reveal unique patterns in the water.

The white catkins that had disappeared reappeared, weaving a strange pattern and then slowly approaching the lenses at the bottom of the water, one after another, the two inconspicuous lenses were like bottomless pits, devouring countless patterns, and finally, as the white catkins slowly disappeared, the whole pool gradually returned to calm.

Until finally, as if it were a pool of stagnant water, Bernard was secretly surprised by this so-called water condensation refining method, but he was surprised to see the glasses shining at the bottom of the water, and Bernard immediately took them out with a wave of his wand.

Leaving the pool, the spectacle lenses, which had a faint glow, relegated to the ordinary, except that they seemed to be a little brighter, and looked no different from ordinary spectacle lenses. However, although the spectacle lens looked very ordinary, the more Bernard looked at it, the more he liked it, and then he couldn't help but walk to the alchemy table and carry out the final processing.
